DHH44, SKBC micro-resistance slow closing silencing check valve
The company's production of H47X/H, DHH44X/H-10/16 type micro-resistance slow closing muffler check valve is mainly used for industrial, urban water supply and drainage pipelines and high-rise residential, high-level hotels, pressurized water pump outlet. In the design of full consideration of the requirements of the use of the environment, the use of inclined plate structure, to achieve no vibration, no noise, smooth operation, to ensure that the hotel, residential environment is quiet, and has the effect of energy saving. The local reverse water is discharged into the system by delaying the closing, which greatly reduces the water pressure impulse of the reverse flow of the pump and eliminates the generation of destructive water hammer peaks. The interception seal adopts nitrile rubber, which has good sealing performance and shock absorption. Features such as wear resistance, long service life and convenient maintenance.
Key words:
Silent check valve is mainly composed of valve body, valve seat, deflector, valve disc, bearing and spring and other major parts, the internal flow path using streamlined design, pressure loss is very small. The opening and closing stroke of the valve flap is very short, and it can be quickly closed when the pump is stopped, preventing huge water hammer sound, and has the characteristics of silent closing. The valve is mainly used for water supply and drainage, fire protection, HVAC systems, can be installed at the pump outlet to prevent back flow and water hammer damage to the pump.
Key words:
H41X, SKHF1X * energy-saving silencing check valve
The muffler check valve is suitable for water supply and drainage pipelines. The valve flap is guided by the central axis at both ends of the inlet. It is flexible in opening and closing and can be installed horizontally or vertically. Valve using spring loaded, its fast closing can effectively eliminate water hammer, good sealing performance, close without noise. It has the advantages of small size, light weight, low fluid resistance, fatigue resistance and long life.
Key words:
44X(SFCV), SKSC4X * rubber flap check valve
Rubber flap check valve is mainly composed of three main parts: valve body, valve cover and rubber flap. The rubber flap is made of steel plate, steel rod and reinforced nylon cloth as the substrate, and the outer layer is covered with rubber. The service life of the valve flap can reach 1 million times. The valve adopts full flow area design, with small head loss, not easy to accumulate chores, easy maintenance and other characteristics. The valve is mainly suitable for water supply and drainage system, can be installed at the outlet to prevent back flow and water hammer damage to the pump. The valve can also be installed on the bypass pipe of the water inlet and outlet pipes of the reservoir to prevent the backflow of the pool water into the water supply system.
